' 3 Claims. (01. 101%360) p This invention relates to printing machinesfor linoleum, textiles and the like.

In the manufacture of linoleum, t'extilesand the like, figures ordesigns are in different colors or the same color to form artisticsurfacesr'The printing is done by what is known as block print ing. Theusual structure for' block'printing consists of a series of dies whichareinked by rollers rotating in a bath in pans supportedby a travel linglinked structure which is intermittently moved back and forth to ink thedie between each stroke while the material is advanced the properdistance for the next operative printing stroke of the die.

In the case of the use of different colors a number of dies must be usedwith the same number of inking rollers and pans forming a lengthy chainand as the motion is intermittent considerable Wear and breakage occurscausing relatively high maintenance costs. In addition, the color mustbe removed from the pans and. new color inserted whenever a change incolor is desired. This time required for such changing materiallyreduces the output for each machine and inf'creases costs.

One of the objects of this invention is to provide a printing machinewherein the inking rolls and pans may be easily changed and where anyone or a group of inking rolls or pans may be i removed and replacedquickly to change the color design.

Other objects of the invention will appear more fully hereinafter.

Referring to the drawings:

Figure 1 is a side elevation of a rear half of a printing machineembodying the principles of my invention.

Figure 2 is a view in elevation of the forward half of the frame of themachine.

Figure 3 is a detail view of the inking roll, pan and carrier inconnection with the printing die.

Figure 4 is a cross sectional view of Figure 3, on the line 4, 4,looking in the direction of the arrows.

Figure 5 is a detail view of the carriage connection disengaged from themotivating rod.

Figure 6 is a detail view along the line 6, 6, of Figure 3, looking inthe direction of the arrows.

In carrying out my invention, I provide a frame 11 carrying printingdies 2. The dies are of the usual construction for block printing. Oneach side of the bed of the machine racks 3 and tracks 4 are provided.The inking rollers 33 for inking dies 2 are adapted to rotate in pans 34supported by carriages having flanged wheels 5 journaled on axles 6carried by frames '7. A pinion gear 8 meshes with rack 3 and gears; oninking roll shaft 10. Gear 3 is adapted to be shifted in slot 13 tomaintain contact between gear 9 on the end of color roll 33 and rack 3in order to main- 0 tain proper contact when the color roll is adjustedin' height to properly kiss the blocks. A frame '7 at one end has yokes15 through which pins 16 are journaled. Pins 16 terminate at their upperends in eyelets 17. Pins 19 operate as stops for springs 18 surroundingpins 16, said springs bearing against one arm of yokes 15 to maintainthe bottom of pins 16 protruding through the lower arm of yokes 15 andin slots 20 in rods 21. Slots 20 function not only as connecting meansbetween frames '7 and rods 21 but also indicate the exact position forthe return of the carriages after removal and upon subsequentreplacement. Without such an indicating means proper synchronization ofthe carriage with the oscillating rod and printing die would not bepossible. Frame 1 has slots 24 with rollers 22 supported by bearings 23therein. Rods 21 are adapted to slide on rollers 22. The constructionshown permits any pan to be used without using the replacing links whichhave been heretofore necessary. Also the carriages and inking rollersmay be readily removed or replaced permitting any combination of pansbeing run or omitted. Rods 21 are motivated by an intermittent mechanismsuch as by levers 26, 27, in cams 28, 29, and spring 30 and driventhrough gearing 31, 32, from a source of power supply. The movement ofrods 21 to the left causes gears 8 to be rotated by racks 3 therebyrotating gear 9 and inking roller 33 and at the same time moves thecarriage and pan 34 and inking roller 33 to the leftto pass under thedie or roll. Upon the completion of the printing by the die or roll,rods 21 move to the right again carrying the carriage '7, pan 34 andinking roller 33 under the die or roll 2 to ink same for the nextstroke. In other words, the inking roller passes intermittently back andforth under the dies or roll 2 to ink same prior to each stroke. When itis desired to change the color it is only necessary to raise pins 16 byeyelets 17 and rotating the pins degrees so that pin 19 rests onshoulder 36 and then to lift off the particular inking roll, pan orcarriage and replace same with another similar device. This can be donerelatively quickly. In addition, as the inking devices are notinterconnected a reduction of wear is accomplished which becomes moreexcessive in the older structures as the devices were enlarged. The sameaction occurring in the old structures as occurs 11;

in the case of a train of railroad cars shunting back and forth whereinthe shock of the stoppage of each preceding car is passed on andincreased by each succeeding car causing considerable stresses in theconnections. In applicants structure each device being secured to therods 21 do not transmit the forces to each other and hence there can bea lightening of mass in the structures and the movement thereof moreeasily consummated.

The dies 2 are of standard construction and the means of operation arethe customary ones and no claim is made in connection therewith.

It will thus be seen that I have provided a method for inking orapplying color to dies or rolls for printing textiles and the like,which will materially effect savings in the power costs,

maintenance costs, and which will more readily permit of changing ofcolor designs without waste of materials and which can be done morecleanly.

What I claim is:

1. In a printing machine for printing linoleum, textiles and the like,an inking roll, a pan for said roll, carriages for said pan and roll, aframe, reciprocating sliding elements sliding in said frame, means forreciprocating said sliding elements, indicating slots in said slidingelements to indicate the proper position of said carriages with respectto said sliding elements, pins carried by said carriages and cooperatingwith said slots to connect said carriages to said sliding elements andposition same, springs for maintaining said pins in said slots.

2. In a printing machine for printing linoleum, textiles and the like, aframe, a plurality of inking rolls, pans and carriages therefore,reciprocating sliding elements sliding in said frame, means forreciprocating said sliding elements, roller bearings carried by saidframe upon which said sliding elements reciprocate, slots in saidreciprocating elements to indicate the proper position of said carriageswith respect to said sliding elements, and latching means carried bysaid carriages and cooperating with said slots to positively connectindividually each carriage with the sliding elements.

3. In a printing machine for printing linoleum, textiles and the like, aframe, an inking roll, a pan for said roll, carriages for said pan androll, reciprocating sliding elements in said frame, means forreciprocating said sliding elements, indicating slots in said slidingelements to indicate the proper position of said carriages, pins carriedby'said carriages and cooperating with said slots to connect saidcarriages to said sliding elements and position same, means forpositively maintaining said pins in said slots and means for positivelymaintaining said pins out of said slots after manual disconnection.
